Title: Shaking-off device of dust in bag filter
Inventor: OMATA YOSHIAKI
IPC: B01D46/04
Filed: 1982-07-30
Abstract: PURPOSE:To reduce cost by a simple construction, and to prevent dust from resticking to a bag, by arranging a device, used for shaking off dust sticking to one row portion of bags, movably on a bag chamber, and shaking off the dust by cutting off an air flow at both sides of a bag. CONSTITUTION:At the start-up of a dust shaking-off operation, a compressed air is supplied from a master valve 33 to drive a wire cylinder 32 thereby a jetting device 18 is moved. When the device 18 arrives at the position of a striker 21, a diaphragm valve 27 is opened, and the compressed air of a header 28 is jetted against a Venturi-tube 29 from a nozzle 22 through an introducing pipe 26. Then a check valve 25 is opened, and air in a cleaning chamber 14 flows into a jetting chamber 24 to be caught up into the compressed air, which shakes off the dust deposited on the bags while passing through the bags from their inner surfaces to their outer surfaces. At this time, as the open parts of both sides of the shaking-off bags are blockaded by blockade plates 30, the dust shaken off by the air, which is being used for dust collecting, is prevented to stick onto both sides of the bags and other bags. The device 18 moves slowly to the next bag even while the dust of a row of bags is being shaken off.

Filed: 1982-08-02
Abstract: PURPOSE:To certainly issue a trigger pulse only when a wave form signal to be practically observed and stored is inputted, by setting plural kinds of upper and lower limit reference compensation voltage. CONSTITUTION:In an input comparison circuit 9', reference compensation voltage and an analogue signal always outputted from a multiplexer circuit 13 are compared by an upper limit and a lower limit comparison circuits 16 while a detection circuit 17 detects the presence of the input signal within a range of upper limit and lower limit reference compensation voltages in the timing of the strobo pulse from a control circuit and, when said input signal is present in said range, the multiplexer 13 is changed over by the control circuit to output the next reference compensation voltage. When operation is repeated and up-to n-times input signals are continuously present within the range of plural kinds of upper limit and lower limit voltages, a trigger pulse is issued. A phenomenon hardly estimated in the timing of generation can be easily stored in a memory area to be analysed.

Title: Sealed bearing and manufacture thereof
Inventor: KONDO HIROMITSU
IPC: F16C33/78
Filed: 1995-05-31
Abstract: PURPOSE: To provide sufficient sealing performance by simple constitution by forming a very small gap in a seal gap against either a rotary side member and a stationary side member, and interposing a seal member formed by solidifying a fluid substance. CONSTITUTION: A shield plate 5 is mounted on the inner diameter of the end part of an outer ring, so that a seal gap 6 is formed between the extreme end part 5a and the outer diameter of the end part of an inner ring 1. Next, the seal gap 6 is filled with a seal member made of resin in fluid state, the member is turned round up to the upper part inside the extreme end 5a, and the member is dried and solidified while rotating the inner ring 1, so as to form a sealing member 7. In this process, shear fracture is generated on the contact part between the sealing member 7 and the inner ring 1, and hence a very small gap 8 is formed. Because the very small gap 8 is remarkably smaller than a gap by general machining, sealing performance is improved, and not only outflow of lubricant to the outside but invasion of a foreign substance such as dust or water from the outside can be prevented.

Title: Shifting apparatus for elongated object and shifting method therefor
Inventor: YAMAGUCHI HIROSHI
IPC: B65B27/10
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To reliably prevent elongated objects from being obliquely moved, by a method wherein a plurality of wedge rods for controlling the movement of the elongated objects are disposed on a straight line in such a manner as to be capable of rising and setting at an edge of a receiving table for receiving the elongated objects, and a central group of the wedge rods is projected before successively projecting adjacent groups of the wedge rods when the movement of the elongated objects is stopped. SOLUTION: In an apparatus for shifting pipes when a group of small-diameter pipes is bundled, wedge rods 182a-182c are all projected on a receiving table 100 during the elevation of a fork for shifting the pipes, and, after the elevation of the fork, all the wedge rods 182 are allowed to set. In the case where a predetermined number or more of pipes exist on a pipe receiving part of the receiving table 100, the four wedge rods 182a, 182b at the central portion are successibly projected before projecting the wedge rods 182c at the end portions, and, thereafter, the central wedge rods 182a, 182b are allowed to set. Thereafter, when a pipe sensor detects that the number of pipes P on the pipe receiving part becomes smaller, the wedge rods 182c at the end portions are controlled to set, thereby preventing the pipes from being obliquely moved.

Title: Recorder, and recording unit and recording head therefor
Inventor: KAWADA NAOKI
IPC: B41J2/21
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain a recorder in which highly accurate high quality printing is carried out at high speed and noncontact output printing can be carried out without selecting the shape of a recording medium while satisfying both reduction in size and safety. SOLUTION: The recorder comprises a transparent electrode 2, a photoconductive film 4 formed thereon, means for supplying ink 6 onto the photoconductive film 4, and a counter electrode arranged in this order. The recorder further comprises a power supply 3 for applying a voltage between the transparent electrode 2 and the counter electrode, and means 5 for irradiating the photoconductive film with a light corresponding to a desired pixel. Since the transparent electrode 2 concentrates the field from the transparent electrode of wire or a fine pattern and minimizes the electrostatic attraction acting on a recording medium, a recorder satisfying both high speed and high quality image output can be realized.

Title: Method for reducing unsaturation in polyol
Inventor: DEBITSUDO TORUPE
IPC: C08G65/02
Filed: 1993-06-04
Abstract: PURPOSE: To easily lower the level of unsaturation by mixing high molecular weight polyoxyalkylenepolyol with certain immiscible extraction compound of a low molecular weight polyol type, and removing the compound from the mixture.  
     CONSTITUTION: Polyoxyalkylenepolyol having a nominal number average molecular weight of 1,000 to 25,000 is mixed with an extracting compound comprising a polyol having a nominal number average molecular weight of 500 at the largest and immiscible with the polyoxyalkylenepolyol (example: ethyleneglycol) or a polyol mixture. Then, polyoxyalkylenepolyol of which unsaturation level is reduced is obtained by separating the extracting compound and the polyoxyalkylenepolyol to remove the extracting compound.
